Just picked up a cat 955L. Need a rebuildable engine for it. It's a cat 3302. Can't afford a "remanufactured", just looking for something solid i can put a lower end kit in. Located in virginia. Also need to find the shop manual for it.
Also, anybody have hints about this machine? Not trying to make a living with it, just want to use it around the farm.
 
Might try iron peddlers in Monroe NC, just north east of Charlotte NC they deal in CAT parts and equipment pretty good folks to deal with. 955's are strong tuff machines they have a lot of break out power
 
It's a 3304. Hints? Avoid running it without the engine side covers. Debris is sucked in and thrown against the core, mashing the fins flat (unless you have a reversible fan). If the transmission is leaking into the final drives, don't worry about it. Just drain it down every day. There's supposed to be motor oil in there anyway, not 90W. Inspect the rubber drive blocks before installing the engine, and replace them if they are not perfect. They never fail when it is warm, dry, sunny, or close to any repair facility. When this coupling goes, ALL operations fail. Don't mess up the arrangement of the shims under the rear engine mounts. The engine must be aligned with the converter input shaft with a reasonable amount of precision, or the life span of the coupling will be shortened. Or worse, angular forces on the converter shaft could risk converter failure. Oil filler tube: You will never stop it from breaking. Just saw it in half, near the bottom, either above or below the first bend out of the timing gear cover. Clamp a piece of rubber hose here. Important fix because tube is positioned over water pump gear, and you can't tell that oil is being thrown out, until you have no oil pressure. Same deal with turbo feed line. Do not omit any clamps, in order to minimize feed line vibration. To minimize broken turbo elbows, do NOT clamp the muffler to the elbow. Instead, have the muffler body securely clamped to the hood. If there is no body clamp on the hood, order one from Cat and weld it on. Make sure the rubber blocks under the rear hood mounts are in good condition. As a general rule, just stay out of second gear on hard surfaces, which is where most of the vibration comes from. 1st or 3rd is fine. Do not ever lend this machine to anybody, unless they're renting it or agree to be liable for repairs. All that being said, it's a good machine and will do what you want it to do, but don't get the idea you can get your money back out of it, just because of a new engine. You may want to rethink this project if the under carriage is wasted, or something like that. I've got a museum-quality 85J7759 that I've been told is only worth 8,500.00. Just something to think about.
 
Got to ask, what's wrong with the engine that prompted you to say you need a 'rebuildible' engine for it? Unless you've got a block with a hole in it, there's no reason that your engine can't be rebuilt quite easily. Even then there are places that carry cores where a bare block can be bought to start the build.

Barring a rebuild it took me one search for a 'CAT D330 for sale' to come up with an add selling one for $5000. At that price I can tell you for a fact it would be cheaper than a rebuilt. Personally I typically price a rebuilt at somewhere around $2000 to $2500 per cylinder, which includes EVERYTHING from the labor to pull, teardown, rebuild, and reinstall, along with machine shop charges and all parts needed to do the job. In that case it would be somewhere from $8000 to $10,000 for a rebuild, or alot more than a good running $5000 'take out'. Now if you did all of the work yourself, other than the stuff a machine shop needs to do, you might come out for less than $5000 for a complete rebuild, but only if you have the tools and the capability to do it that way.

Good luck.

A 955L is very good machine if looked after. Cat kept them around when the 953's first came out. Depending on the year, I think early 955's used a different engine and the later ones used the 3304 which is a very good engine. I think a D6 uses the same engine.
 
Nik Is Ray Walker still living or is son running the place ? Knew Ray 30 years ago. Seems like he had a guy with a name like Shirley or a woman,s name that did a lot of the trading..Old memories
